IMPROVEMENT IN THE FBMATION uOF .TOINTS OF STEL 0R IRON PLATES.

`To ALL` WHOMIT MAY coNeERN:

I Beit known `thatV I, E. T. LIGON, of Demopolis, in the county of Marengo, and State of Alabama, have "invented a new and improved Combinationof Steel or Iron Plates with Copper; and I do hereby declaro that the following is a full, clear, and exact description thereof, which will enable those slrilled'in the art to make and use the same, reference being hadtoy the accompanying drawings, forming part of this specification.

' The present invention relates toan improved combination of steel or iron [plates with copper, and it con-v sists in so bending the edges of steel `orviron plates, coated upon their outsidewith copper, in any suitable manner, as, for instance, -bymy improved mode, for which an application for Letters Patent is n owipendingbefore the United States Patent O'liicc, that, when such plates are laid or placed edge to edge, not only will a eontinn'ous'joint of copper he left, but all the rivets and `edges of the plates will be upon the inside, if to a l vessel such plates'are appliedor attached.

As copper is much softer than steel or iron, it is obvious that, when the plates are riveted, as copper is next to copper', la more perfect jointA is the result, and one less liable'to oxidation than steel or iron. The seams or joints to the several plates, produced as above described, may, it' so desired, upon theroutsidc to such plates, be filled with solder, whereby additional strength is given to the plates, and then-attachment toeach other, as well as a smooth and unbroken surface presented to the sea, if the plates are applied toa vessel, thus greatly vvreducing the frictionA thereon.

iBy the turning or bending in of the edges ofthe plates, when secured together as described, they are far stronger, and a more uniform and even .strength throughout the entire plates secured, rendering-thorn1 in a great measure, self-sustaining, without any packing.

The mode of-securing together stoel or iron plates coated with copper, above described, is more especially designed for vessels, but itV is obvious it may he applied to other purposes, .In the accompanying plate of drawings, my improved-combination of steel or iron plates coated with copper is illustrated-- Figure -lbeing a view of a series of the saine upon thcir'inside.

-Figure 2, a view of the same upon the-outside; and `Figure 3, a transverse section in the plane of the line :e w, tig. 1.

Similar letters of' reference indicate corresponding parts. A A, the drawings, represents a series of plates, that, alo'ngthcir edges, B, are bent over and thon secured together by rivets, or in any other suitable manner. These plates A are made of steel or iron, and upon orne side are coated with copper, and by such copper surface, at theirbentover edges, they are in con tact with each other, forming a copper joint,l-and one thc advantages oi Whicbha-ve been hcreibeforereierred to.

I claim as new, and desire tovsecurcby Letters Patent- The application of the coating of copper to the bent-over edges ot' steel on iion pla-tes, as descri'bed,for the purpose ofA forming a. tight joint, less liable to oxidation than steel cr iron, as herein shown and described.'` n. T. Liteon.
